"Our exit from Wilton Mall happens at a time when we've seen many moviegoers flocking to locations with a greater regional attraction and offering premium amenities such as our recently opened Regal Premium Experience (RPX) at Clifton Park to the south," Gallagher said in an emailed statement. She said the company does not release data on theater attendance for specific theaters.

Construction on the building is ongoing and Bonacio said Tuesday it is on track to open in the beginning of July.

Bonacio said Wilton Mall's aging theater, which doesn't have any of the bells or whistles like large-format screens and stadium seating of newer theaters, was one of the reasons he decided to build a new theater downtown. "That's the reason that we're doing the investment that we are, that's a little bit of a dated cinema out there."

Regal also plans to upgrade the theater at Aviation Mall into a 12-screen theater with a large-format RPX screen like Clifton Park.

Gallagher said the Wilton and Latham theaters' employees have been offered jobs at Regal's Clifton Park theater.

Wilton Mall Manager Mike Shaffer said via email Tuesday: "We look forward to the opportunity to bring a new compelling concept to this space. Any time we can re-lease well-positioned space at Wilton Mall, we view it as a chance to bring new energy to our Shopping Center."
